Shortly after release, the film was sold to an exploitation producer who added raunchier scenes to give the film more appeal on the drive-thru grindhouse circuit. Amongst the changes made to this version (which was renamed Miss Jessica is Pregnant) were a shot of Carl spotting Jessie naked from behind in the bath near the beginning after he clears the dinner table, a sex scene between two revellers from the bar in the basement of the gas station after Carl manhandles Jessie back into the car, and a sex scene between Carl and Jessie in the field which was much more ambiguous in the original.
When restored in the late 2010s, the brief shot of Jessie naked in the bath was retained, but the other sex scenes (including some shot but not included in either version) can only be seen in the supplemental material on the Blu-ray releases.
